Hello everybody , I am kind of new to this world.
I have made some investments in the altcoin , I think I have some good coins wich I can trust more in my portofolio like PRL , Onions , Dubai Coin and in my opinion Potcoin also.
I also have some coins like Verge , Power Ledger , Dogecoin in wich I dont have that much trust but I really just can't sell them , I'm like afraid that they will rise good and I will regret selling them.
I have some coins on my mind wich I will also like to add to my portofolio but it seems like my only option is to deposit more fiat money and buy them also , because I really can't convince myself to sell any coin

.
Do any have this problem, have this fear of selling altcoins before they rise from the buy price , I really can't give up on anything I buy If it doesnt make a huge jump to generate some profit

I think most of us have almost the same problem like you and its problem comes when our portofolio go down.
But like you said, its difficult to convince ourselves to sell them and buy the new altcoin. I think hold them all first is better.
